(Jacq.) Griseb., Fl. Brit. W. Ind. 226.1860 Tree, to 30 m tall and 1.5 (3) m dbh, branched from near the ground, the crown widely spreading; outer bark with rough fissures; wood reddish-brown; branchlets usually glabrous in age. Leaves sometimes several at a node, bipinnate with 4-15 pairs of opposite pinnae, puberulent; petioles 4-8 cm long, with a round gland near middle of upper surface; rachis and pinnular rachis with glands at insertions near apex; leaflets in 15-30 pairs per pinna, +/- oblong, decidedly inequilateral, acute at apex, rounded at base, 8-15 mm long, 2-4 mm wide, sometimes glabrate. Inflorescences axillary in groups of 1-3, white, puberulent to glabrate throughout, 2-4 (6) cm long; heads globular, ca 2 cm wide; bracts minute; flowers sessile, green; calyx 2-3 mm long, the lobes to 0.5 mm long, subacute; corolla 5-6 mm long, the lobes to 1.5 mm long, subacute; stamens to 12 mm long; filaments united in basal half; anthers white; style +/- equaling stamens. Legumes reniform, flat, glabrous, 4-6 cm wide, curved into a nearly complete or overlapping circle to 11 cm diam; seeds ovoid-compressed, 1.5-2 cm long, to 1 cm wide, smooth, brown, bearing a lighter submarginal ring on either flattened surface. Croat 7365, 8708. Uncommon, persisting as large trees in areas of previous cultivation. Flowers principally in the dry season (January to May). The fruits mature one year later in the dry season. The tree is leafless for a short time before flowering and produces new leaves at about the same time as the flowers. Neal Smith (pers. comm.) reports that an individual of E. cyclocarpum flowered in January in three consecutive years. Tropical Mexico to northern South America; introduced into the West Indies and West Africa. In Panama, known from tropical moist forest in the Canal Zone, Bocas del Toro, Chiriqui, and Darien; reported also from premontane moist forest in Panama (Tosi, 1971). See Fig. 260.
